Moreover, this embodiment of the present invention may further have a non-volatile storing part that stores the emergency signal output by the emergency signal outputting part with a non-volatile memory, wherein the logic circuit part may store the emergency signal at least until a process of storing the emergency signal by the non-volatile storing part is completed. Thereby, even in a case where, for example, change or disconnection of supply voltage occurs upon vehicle collision and the emergency signal is not stored by the non-volatile storing part, the emergency signal can be surely stored and retained by the logic circuit part. Accordingly, the emergency report can be surely conducted when the vehicle is in an emergency status.
This embodiment of the present invention may further have a non-volatile storing part that stores the emergency signal output by the emergency signal outputting part with a non-volatile memory, wherein the logic circuit part may store the emergency signal at least until the non-volatile storing part erases storage of the emergency signal. Thereby, the emergency signal can be stored and retained in at least either one of the non-volatile storing part or the logic circuit part. Accordingly, the emergency report can be surely conducted when the vehicle is in an emergency status.
This embodiment of the present invention may further have an emergency signal determining part that determines whether the emergency signal is stored by the logic circuit part, wherein an emergency report may be conducted with respect to the outside when the emergency signal is determined as being stored by the emergency signal determining part. Thereby, the emergency report can be surely conducted with respect to the outside based on the emergency signal stored by the logic circuit part.
This embodiment of the present invention may further have an emergency signal determining part that determines whether the emergency signal is stored at least by either one of the logic circuit part or the non-volatile storing part at a time of reactivating the apparatus, wherein an emergency report may be conducted with respect to the outside when the emergency signal is determined as being stored by the emergency signal determining part. Thereby, even in a case where, for example, change or disconnection of supply voltage occurs upon vehicle collision and the apparatus being reset is reactivated, the emergency report can be surely conducted with respect to the outside based on the emergency signal stored by at least either one of the logic circuit part or the non-volatile storing part.
This embodiment of the present invention may further have a location detecting part that detects a current location of a vehicle, wherein the logic circuit part may store the current location of the vehicle detected by the location detecting part together with the emergency signal. Thereby, in a case where, for example, change or disconnection of supply voltage occurs upon vehicle collision, information of the current location of the vehicle together with the emergency signal can be surely stored and retained by the logic circuit.
In this embodiment of the present invention, the emergency signal outputting part is, for example, a passenger protecting apparatus for protecting a passenger, wherein the emergency signal is an activation signal output when activating the passenger protecting apparatus.
In this embodiment of the present invention, the passenger protecting apparatus is, for example, an airbag apparatus, wherein the activation signal is an airbag deployment signal.

BEST MODE FOR IMPLEMENTING THE INVENTION
Next, a best mode for implementing the present invention is described by presenting embodiments while referring to the attached drawings.
FIG. 1 is a block diagram showing a configuration of a system of an emergency reporting apparatus according to an embodiment of the present invention. The emergency reportingapparatus10 according to this embodiment is mounted on a vehicle. For example, in a case where a vehicle is in an emergency status (e.g., vehicle accident, vehicle fire), theemergency reporting apparatus10 reports an emergency to the outside (e.g., information center).
Theemergency reporting apparatus10 is configured having an emergency reporting ECU (Electronic Control Unit)2 as its center for executing, for example, a control process of theemergency reporting apparatus10.
Theemergency reporting ECU2 includes: a CPU (Central Processing Unit)2afor executing various processes in accordance with a control or calculation program along with controlling each part of theemergency reporting apparatus10; anon-volatile memory2bfor storing data processed by theCPU2aand rewriting data; and a logic circuit part2dfor performing, for example, a storing process, a calculating process, or a determining process on various data by using alogic circuit2c.
For example, EPROM (Erasable Programmable ROM: Flash ROM), or EEPROM (Electrically EPROM) is used as thenon-volatile memory2b.
The logic circuit part2dperforms a storing process, a calculating process, or a determining process on digital signals by using thelogic circuit2c. Thelogic circuit2cis configured having, for example, plural transistors, diodes, and resistors. A programmable logic IC (Integrated Circuit) is used as thelogic circuit2c. It is to be noted that thelogic circuit2ccan perform the storing process at an extremely high speed by electrically latching the signals. Furthermore, since thelogic circuit2ccan perform the storing process using small electric current, thelogic circuit2ccan retain storage for a long period.
Avehicle power source3 is connected to theemergency reporting ECU2 for supplying power to theemergency reporting ECU2. Furthermore, acondenser4 is connected to theemergency reporting ECU2 in parallel with thevehicle power source3.
Apassenger protecting apparatus5 is connected to theemergency reporting ECU2 for protecting a passenger. Thepassenger protecting apparatus5 is activated and outputs an activation signal to theemergency reporting ECU2 in a case of protecting a passenger.
Theemergency reporting ECU2 recognizes that a vehicle is in emergency status, for example, upon receiving an activation signal from thepassenger protecting apparatus5. It is to be noted that a vehicle being in an emergency status refers to, for example, a case where a vehicle accident has occurred (e.g., a vehicle colliding with an obstacle).
Thepassenger protection apparatus5 includes, for example, a seatbelt apparatus for confining a passenger to a seat of a vehicle, an airbag apparatus for deploying and inflating an airbag for absorbing shock applied to a passenger, a steering apparatus having a shock absorption mechanism installed in a steering column, a brake pedal apparatus for averting upon generation of shock and absorbing the shock, a PCS (Pre Crush Safety) control apparatus and any other apparatus for ensuring safety of the vehicle.
For example, in a case where an acceleration sensor or the like detects shock of the vehicle, the airbag apparatus being thepassenger protecting apparatus5 is activated to deploy the airbag and output an airbag deployment signal that is the activation signal to theemergency reporting ECU2. It is to be noted that the airbag deployment signal comprises, for example, serial digital data.
The activation signal transmitted from thepassenger protecting apparatus5 is, first, stored and retained in thelogic circuit2cof the logic circuit part2dof theemergency reporting ECU2. Furthermore, the activation signal is transmitted from thelogic circuit2cto theCPU2a. TheCPU2aperforms writing and storing in thenon-volatile memory2bbased on the received activation signal.
It is to be noted that, as described above, the storing process of the logic circuit part2d, as described above, is performed at an extremely high speed compared to the storing process of thenon-volatile memory2b(e.g., requiring several tens milliseconds for writing data). Therefore, the logic circuit part2dcompletes the process of storing the activation signal before thenon-volatile memory2bcompletes the process of storing the same activation signal.
Furthermore, the logic circuit part2dis configured to store and retain the activation signal at least until the process of storing the activation signal is completed by thenon-volatile memory2b. Thereby, in a case where, for example, disconnection of thevehicle power source3 causes an interruption in the process of storing the activation signal by thenon-volatile memory2b, the same activation signal can be surely stored and retained by the logic circuit part2d.
Acommunication apparatus7, which performs data reception and transmission with the outside (e.g., information center1), is connected to theemergency supporting ECU2 via acommunication network6. It is to be noted that thecommunication network6 includes, for example, a regular telephone network, a mobile telephone network, and the Internet. The mobile telephone network includes, for example, a communication base station.
Theemergency supporting ECU2 reports an emergency by transmitting an activation signal of thepassenger protecting apparatus5 to, for example, theinformation center1 via thecommunication apparatus7 and thecommunication network6. It is to be noted that theemergency supporting ECU2 may be connected to a GPS (Global Positioning System) receivingapparatus8 for detecting a vehicle's current location. TheGPS receiving apparatus8 transmits detected location information regarding the current location of a vehicle (e.g., address, telephone number, latitude, longitude) to theemergency supporting ECU2. In this case, thenon-volatile memory2band the logic circuit part2dof theemergency supporting ECU2 may store the location information of the vehicle together with the activation signal. Then, theemergency supporting ECU2 transmits the location information of the vehicle together with the activation signal to theinformation center1 via thecommunication apparatus7 and thecommunication network6. Thereby, theinformation center1 can recognize that the vehicle is in an emergency state along with recognizing the current location of the vehicle. Accordingly, precise and swift action can be taken in response to the vehicle being in an emergency status.
TheGPS receiving apparatus8 performs calculations and detects location information regarding the current location of a vehicle based on positioning radio waves from plural GPS satellites. Furthermore, the location information may be detected from a navigation apparatus mounted on the vehicle or a GPS receiver built inside a mobile phone of the user.
Theinformation center1 recognizes that the vehicle having theemergency reporting apparatus10 mounted thereon is in an emergency status when receiving an activation signal of thepassenger protecting apparatus5 from theemergency supporting ECU2. Then, theinformation center1, based on the received activation signal and location information of the vehicle, reports the emergency status of the vehicle to aregistration destination9 registered beforehand, such as a police department, a fire department, or the residence of the user. Thereby, emergency actions such as passenger rescue can be swiftly and surely performed for the vehicle having theemergency reporting apparatus10 mounted thereon.
Furthermore, based on the activation signal, the location information of the vehicle, and pre-registered information (e.g., emergency contact address), theemergency supporting ECU2 may be configured to directly report the emergency to the registration destination9 (e.g., police department, fire department, user's residence) without the intervention of theinformation center1.
Furthermore, theCPU2aof theemergency reporting ECU2 may erase the memory of the activation signal from thenon-volatile memory2band thelogic circuit2cof the logic circuit part2dwhen determining that the reporting of the emergency has been completed by thecommunication apparatus7. This surely prevents erroneous reports after the completion of the emergency report.
It is to be noted that there may be a case where theCPU2aof theemergency reporting ECU2 is reset by, for example, disconnection of thevehicle power source3. In this case, if theCPU2adetermines that an activation signal is stored and retained in either one of thenon-volatile memory2band thelogic circuit2cof the logic circuit part2dupon re-activation, the activation signal is transmitted to theinformation center1 via thecommunication apparatus7. Thereby, emergency can be reported more surely.
Next, an example of a configuration of thelogic circuit2cof the logic circuit part2dis described in detail.
For example, as shown inFIG. 2, thelogic circuit2cincludes aserial determination circuit20 for extracting specific data (e.g., the value of the 3rdbit=1) from an airbag deployment signal comprising serial data transmitted from the airbag apparatus (passenger protecting apparatus)5, alatch circuit21 for retaining the specific data (value of 3rdbit=1) extracted by theserial determination circuit20, and an ANDcircuit22 for performing a determination process using logical conjunction based on the specific data (value of 3rdbit=1) stored and retained by thelatch circuit21 and, for example, a signal input from theCPU2a(SeeFIG. 2).
It is to be noted that theCPU2amay input a signal=1 to the ANDcircuit22 immediately after detecting a vehicle speed with a vehicle speed sensor for preventing erroneous reporting by theemergency reporting apparatus10.
TheCPU2a, upon receiving a value=1 from the ANDcircuit22 of thelogic circuit2c, transmits an activation signal to theinformation center1 via thecommunication apparatus7 and thecommunication network6. It is to be noted that the configuration of thelogic circuit2cis one example, and other arbitrary circuit configurations may be applied as long as the configuration has the above-described functions.
FIG. 3 is a diagram showing, in chronological order, an example of changes of supplied voltage supplied from anemergency reporting ECU2 from the time of vehicle collision.
As shown inFIG. 3, in a case of a vehicle accident (e.g., a case where a vehicle collides with an obstacle), various fuses of the vehicle melt to change the voltage of the power source of the vehicle. This change of voltage causes the supply voltage supplied to theemergency supporting ECU2 to change (1). In some cases, the supply voltage becomes lower than the least operation voltage necessary for operating the emergency supporting ECU2 (2). In other cases the supply voltage becomes disconnected (3).
Accordingly, theCPU2aof theemergency reporting ECU2 is reset, to thereby lead to a risk of interrupting each process in theemergency reporting ECU2. Furthermore, the phenomena such as the change or disconnection of power supply occur in a short period such as immediately after collision of the vehicle. Therefore, as described above, the process of storing an activation signal transmitted from thepassenger protecting apparatus5 being performed by thenon-volatile memory2bof theemergency reporting ECU2 may be interrupted before the process is completed, thereby leading to a risk of being unable to store the activation signal in thenon-volatile memory2b.
In such a case, with the conventional art, there is a risk of the emergency not being reported when the emergency reporting ECU is reactivated since the activation signal, which should have be stored in the non-volatile memory, is not stored.
In contrast, theemergency reporting ECU2 of theemergency reporting apparatus10 according to an embodiment of the present invention stores and retains the activation signal transmitted from thepassenger protecting apparatus5 in thelogic circuit2cof the logic circuit part2doperating at low voltage and being capable of performing a storing process at high speed. Then, theCPU2awrites and stores the activation signal in thenon-volatile memory2b.
Accordingly, even in a case of being unable to store an activation signal in thenon-volatile memory2bof theemergency reporting ECU2, the same activation signal can be surely stored and retained by thelogic circuit2cof the logic circuit part2d. Therefore, theCPU2aof theemergency reporting ECU2 can surely report emergencies to theinformation center1 based on the activation signal stored and retained in thelogic circuit2cof the logic circuit part2d.
Next, a flow of control processes of the emergency reporting apparatus according to an embodiment of the present invention is described in detail.FIG. 4 is a flowchart showing a flow of control processes of anemergency reporting apparatus10 according to an embodiment of the present invention.
For example, when a vehicle collision occurs (S100), theairbag apparatus5 is activated in accordance with the shock detected by an acceleration sensor activated so as to deploy an airbag and protect the passenger. At this instant, theairbag apparatus5 outputs an airbag deployment signal to the emergency reporting ECU2 (Step S110).
The airbag deployment signal transmitted from theairbag apparatus5 and received, by theemergency reporting ECU2 is stored and retained in thelogic circuit2cof the logic circuit part2d(S120). Thus, even in a case where theCPU2ais reset due to a change of supply voltage to the emergency reporting ECU2 ((2) inFIG. 3), thelogic circuit2cof the logic circuit part2dsurely stores and retains the airbag deployment signal without being affected by the change of supply voltage ((4) inFIG. 3) since thelogic circuit2cof the logic circuit part2doperates at low voltage and is capable of performing a storing process at high speed.
Furthermore, when the supply voltage to theemergency reporting ECU2 becomes steady and reaches a value which is no less than a predetermined value, theCPU2ais reactivated by performing, for example, an initial operation ((5) ofFIG. 3). The reactivatedCPU2acauses thenon-volatile memory2bto store the airbag deployment signal based on the airbag deployment signal stored in thelogic circuit2cof the logic circuit part2d(S130).
When theCPU2adetermines that the process of storing the airbag deployment signal ((6) ofFIG. 3) has been completed by thenon-volatile memory2b, theCPU2aerases the airbag deployment signal stored and retained in thelogic circuit2cof the logic circuit part2d(e.g., resetting a signal retained in thelatch circuit21 and changing the retained value from 1 to 0) (S140).
Then, theCPU2aof theemergency reporting ECU2 starts an emergency report by transmitting an airbag deployment signal to theinformation center1 via thecommunication apparatus7 and the communication network6 ((7) ofFIG. 3).
It is to be noted that, even in a case where disconnection of the vehicle power source occurs after theemergency reporting ECU2 has starting the emergency report ((3) ofFIG. 3), the reactivatedCPU2acan surely resume the emergency report by reading out the airbag deployment signal stored and retained in either thenon-volatile memory2bor thelogic circuit2cof the logic circuit part2d.
As described above, with theemergency reporting apparatus10 according to an embodiment of the present invention, theemergency reporting ECU2 stores and retains the activation signal transmitted from thepassenger protecting apparatus5 in thelogic circuit2cof the logic circuit part2d. Then, the same activation signal is written and stored in thenon-volatile memory2bby theCPU2a.
Thereby, even in a case where an activation signal cannot be stored in thenon-volatile memory2bof theemergency reporting ECU2 due to change or disconnection of the above-described supply voltage caused by, for example, a vehicle collision, the same activation signal can be surely stored and retained in thelogic circuit2cof the logic circuit part2d. Therefore, theCPU2aof theemergency reporting ECU2 can surely conduct an emergency report with respect to theinformation center1 based on the activation signal stored and retained in thelogic circuit2cof the logic circuit part2d.
The present invention is not limited to the embodiments explained heretofore, but various variations and modifications may be made without departing from the scope of the invention.
For example, according to an embodiment of the present invention, collision of a vehicle may be estimated based on a signal from a vehicle sensor mounted on the vehicle such as acceleration of the vehicle detected by an acceleration sensor, speed of the vehicle detected by a vehicle speed sensor, or an image taken by a camera. More specifically, theemergency reporting ECU2 may further include a collision determining part for determining collision of a vehicle based on signals from these vehicle sensors, so that signals regarding collision determined by the collision determining part are input to the serial determiningcircuit20 of thelogic circuit2cof the logic circuit part2dand retained in thelatch circuit21.
Although the logic circuit part2dis installed in theemergency reporting ECU2 in the above-described embodiment of the present invention, the logic circuit part2dmay be configured in a manner provided outside of theemergency reporting ECU2.
INDUSTRIAL APPLICABILITY
The present invention can be used for an emergency reporting apparatus that reports to an information center, for example, in a case where a vehicle accident occurs. There is no limitation on the appearance, weight, size, or running performance of the vehicle to which the emergency reporting apparatus is mounted.
The present application is based on Japanese Priority Application No. 2006-047706 filed on Feb. 24, 2006, with the Japanese Patent Office, the entire contents of which are hereby incorporated by reference.
